Seeing intelligence

I have always said that one can literally see that a person is more intelligent than the norm by looking at their eyes. I wonder if that observation was based on subconsciously picking up on large pupil size:
A person’s intelligence and brain function correlates to the size of their pupils, a new eye-popping study by US researchers suggests. The study claims that the larger the pupil, the smarter its owner. Cognitive abilities like attention control, fluid intelligence and working memory capacity have been linked to baseline pupil size by researchers at Georgia Institute of Technology, who conducted several large-scale studies involving over 500 participants.

First, they calculated the average pupil size of each of the participants — aged between 18 and 35 years old — using a special tracking device with a camera linked to a computer. Normally, a constricted pupil — the black circular aperture in the center of the eye — is two to four millimeters in size, and fully dilates to up to eight millimeters. 

The participants were then offered a series of cognitive tests measuring their abilities to stay focused and control attention while being intentionally distracted, to reason through new problems and remember new information. The laboratory was kept dim in order for the pupils not to constrict in response to light. 

“We found that a larger baseline pupil size was correlated with greater fluid intelligence, attention control and, to a lesser degree, working memory capacity,” researchers concluded, with their findings published in the June issue of the Cognition international journal.

I tend to perceive intelligence in the eyes as an active awareness, or in some cases a liveliness, that doesn't necessarily translate to the person's expression, tone, or behavior. Not every intelligent person shows this, but I've never met anyone who did who didn't later prove to be intelligent. It might also explain why people instinctively avoid eye contact when they don't want to indicate that they are anyone out of the ordinary.

I am not smart by any means, but if this was true, I would never have been even able to learn proper Hungarian or any math that requires multiplication, much less a foreign language.

I can think of the pupil expanding when someone is really interested in something as being valid, so perhaps a rather dense person never really gets that intellectually invested and thus that shows in the pupils never expanding.

Maybe this should be tested by showing the same people an episode of recent Hollywood media and measure if the reverse is true too and the well performing test subjects now show total lack of interest, while the dumb ones look with wide eyed adoration at the electric Swede.

I attended a seminar training on evaluating truthfulness, in formal settings like depositions.

Parts of it are things like looking for disconnected or out of order emotions and reactions (hitting the table first then flustered facial expression after, and that sort of thing).

But the best consistent thing to watch for is eye movements. People have quadrants they tend look away towards differently for remembering or visualizing or fabricating.

I have a hard time with eye contact. I know it’s the right way to have a conversation, but it seems unnatural? Most people don’t make eye contact when talking to me... so it feels weird trying to make eye contact with others.

Already being socially awkward, I can’t tell if I’m really supposed to look in their eyes or if that just makes me more weird to them.

Dilated pupils go with being relaxed (or turned on) - it's a parasympathetic NS reaction. It's like a powerful v8 idling up a steep mountain pass towing a trailer not even trying vs a little 4 cylinder maxed out on the same road, starting to overheat.

This is very different to bright / lively eyes vs. dull eyes, which as Atikkabear notes can be a sign of engagement or taking the ticket (or even possession).

That's interesting. I know that I can see significantly better in very low light than can my wife. We often walk at dusk, and I make sure that she carries a flashlight to avoid stumbles. I always thought that she just had a lower number of rods in her retina. It never occurred to me that the pupil base size differed that much from person to person, so it might be that as well. So, is someone going to produce a facial recognition program for potential employers to eliminate the pencil point pupil types from consideration?

It's hilarious watching people try to explain away lack of intelligence by citing environmental, emotional, and resource limitations (outside of obvious brain damage, such as due to severe protein deficiencies.).

No. Intellect grows strictly by challenging it. leading a happy, content, and unchallenging life leads to stunted intellectual growth. Obstacles are there to be overcome, not as excuses for being stupid.

Science proves once again something known commonly. It's the reason "romantic " settings are often low light affairs. Your pupils dilate, and in a redponse Pavlov would be proud of, you begin to show more interest in the objects and people around you. I remember at discovering science discovering known things as a teen when I saw a newspaper article touting a local scientist had "proved" squirrels fake burying nuts to through birds off of where they actually do bury them. As a squirrel hunter, I had personally seen this behavior for a decade earlier.

To be fair, successful used Car salesmen, while often lacking certain ethics, tend to be much smarter than most of the people they are selling to. Intelligence and morality do not necessarily move hand-in-hand, especially when you add a bit of ignorant intellectual arrogance into the mix.

That's one of the reason university professors are so out-of touch. They really ARE much smarter than most of those they deal with...but their intellectual arrogance is so extreme that any sort of fact that displaces their favorite oh-so-elegant theory of reality is obviously stupid, or they would have thought of it first.

The laboratory was kept dim in order for the pupils not to constrict in response to light.

“We found that a larger baseline pupil size was correlated with greater fluid intelligence, attention control and, to a lesser degree, working memory capacity,”"


Devil's Advocate: The obvious correlation-not-causation would be that more intelligent people tend to have indoor jobs rather than outdoor ones, and are therefore more adapted to darkness than sunlight, with correspondingly larger pupil size in the same lighting conditions. And yes, there are easily enough midwits to make this the rule.

"it brings comfort to know that average people have an in-built instinctive bullshit detector when the midwits lie about how smart they are."

Unfortunately the midwit is still more intelligent than the average person, so you're going to get some equivalent of the "black magic" response, "I know you're BSing me, but I don't know how I know".

Blogger Azure Amaranthine June 08, 2021 9:46 AM  

At any rate, pupil size may be an indicator in its own right, but you'd have to cross reference against information about peoples' normal living/working environmental lighting, and lens plasticity/elasticity by age to get a better read.

We see by focusing, which means ignoring most of the picture, and our brains operate the same way. We think by focusing, slicing things into categories, setting things into what are for most people in practice ritualistic orders of operations. This means excluding any patterns we don't recognize or can't understand. Most of the world is the darkness of the unknown, and swimming with black swans, the area that most people don't even recognize they don't know, and haven't ever considered.

A larger picture is more comprehensive and complex, but beware that it's still just a stunted glimpse of the reality.

I wish my IQ was a little higher (130). Smart enough to be successful in life, but frustrating when I can't distill intuitive concepts clearly. When someone like Vox or Bruce Charlton nails it, I rejoice "That's it! That's what I was thinking/trying to say!" Just bright enough to be dumb, but my entire life, even as a child, I receive comments about my intense blue eyes specifically.

Personal experience I think may be related: people have always really liked me or really hated me (especially women). I didn't recognize it until young adulthood. Once I did, it became comically predictable.

One head nurse who fucking hated me, but I am certain I could have bent over the desk anytime, found out that I used to be a police officer. She literally blurted out "OMG, that's it, that's why I hate you. My dad was a cop and you have cop eyes." She paused in horror as she realized the politically incorrect official line she had crossed. Never had any more problems with her. Guess it was good for her soul?

Another nurse, who made my life hell in the ER for months, randomly showed me a pic of her ex husband on her phone one day. She said "You look exactly like him." Now I literally looked nothing like him in any way. I made a point to stare into her eyes and simply replied "You have great taste." She was my bestest puppy dog friend ever after.

Life is viewed through the eyes. Anyone else have a similar experience?

Blogger Reziac June 08, 2021 4:05 PM  

This study may have its merits, but it is not well-designed, as it fails to control for two common physical influences on pupil size:

1) myopia. The more myopic, generally the larger the pupil -- trying to compensate for insufficient data by increasing input.

2) thyroid status. Hypothyroidism weakens sphincter muscles, making them unable to fully constrict; this directly causes larger pupil size, since the iris is a sphincter. (Low thyroid also negatively impacts brain function, eg. "brain fog" and in young children, mental retardation.)

That you can tell a lot about someone by their eyes, tho -- that's not in question. Most notably, look at galleries of perps and Antifa types: their eyes uniformly express "screw you", much as galleries of low-IQ types express "no one home".

Blogger S1AL June 08, 2021 4:31 PM  

The distinction of "attention control, fluid intelligence and working memory" is an interesting set. Working memory, in particular, is highly independent of aspects of intellect.

That said, I'm guessing the "liveliness" has more to do with micro-expressions in the facial muscles around the eyes, but that's just a guess.

Touche. Of course this is pupil size, not eye size, but I get the joke.

After read a little further in the Scientific American article covering this, and researching Daniel Kahneman on whose work this is based, I'm feeling pretty good about taking up the skeptic's mantle.

From the article:
"As one example of an attention control test, participants had to resist glancing toward a bold, flickering asterisk on one side of a computer screen and instead rapidly look in the opposite direction to identify a letter. The letter would disappear within moments, so even a brief eye movement toward the flickering asterisk could result in missing it. Humans are primed to react to objects passing through their peripheral vision—it’s what once allowed us to spot a predator or prey—but this task required participants to redirect their focus from the flicking asterisk to the letter."

You hear that? A bold, FLICKERING asterisk. That doesn't seem like a test devised by a high school sophomore at all. Those guys clearly f-ing love science.

I agree. It probably applies to other mammals. I've observed cats preying on small animals enough to see that their pupils dilate before they pounce. I can't think of anything more challenging than the hunt, except maybe living in repentance for being a sinner.

The short of the long of it is that intelligent mammals' pupils dilate when challenged. Similarly, a liar's pupils may dilate when telling a lie.

Yes!! I've always thought this. Almost as if you can see the "technical difficulty screen" in their eyeballs. We usually do the same test for livestock and pets. If you can look into their eyes and hear the radio static going on in their gorked brain, hard pass.

That's how my husband won me. I got locked-in eye contact, and a wink across a crowded room. Now we have 5 acres and 4 kids.

Ohhhh...

This is a Daniel Kahneman work? You can just reject it as garbage out of hand.

It's true. The saying "lights are on, but nobody is at home" didn't come from

I frequently observe my husband not making eye contact - I used to think it was rude but now I think he just doesn't need approval or influence. He's intelligent, very much his own person.

I was in the jury on a murder trial over 20 years. The young black perp had a certain deadness to his eyes that seemed to me more than just his pride putting in a brave show of indifference to the proceedings.

wide eyed adoration

Heh, I was thinking about that - the wide eyed look, I suspect it makes your pupils look smaller by increasing the perceived size of the rest of the eye, thereby making the "wide-eyed" person look dumber.

Eye pupil dilation can also indicate an individual's awareness, general state of ease, and of course love. When I gaze into the eyes of the people I love I can sometimes see their pupils dilate in response. But yes, your assessment at the end there is what I have deduced to be the most reliable visual intelligence que.

She adds "Clare Bell had it right in the first two books of her *Ratha's Creature* series. It's a shame she got woke and spoiled the series"

@12 It is said that men when talking with one another as friends will break eye contact from time to time as maintaining eye contact is subconsciously confrontational and can signal hostility or aggression.

When talking to a car salesman it is probably good to keep eye contact with him and see it as a challenge and the sales process as conflict, because it is. That sort of aggressive mindset needs to be on the part of the buyer, if he is trying to get the best deal out of it.

I am not convinced about intelligence. I am certain of a vivacious nature. I look for it above all things. I rarely see it these days. I will never stop seeking. Though, when people get to a certain age, perhaps... we cannot develop that in others anymore. Though, there is something wrong with this generation? No, it's... not just the generation. It's many of the people of this time, of all generations. Something died in them.

I'll keep seeking, even if for a moment of congenial companionship never to be repeated. It is enough.

Blogger Brother Deke June 09, 2021 8:49 AM  

I haven't thought long enough about it, unfortunately.

I don't know about gauging intelligence, however, I can tell that someone is stupid by looking in/at their eyes.

Feline eyes' pupils grow wider to allow the maximum amount of light in, due to the hunted having just as much power and reflex action (in their own way) as the hunter does. They need all the advantage they can wrest. I've since mice stand their ground and I've seen rats win.

You'll notice you won't see this dilation as much in bored or disinterested cats who are just toying or playing with their prey for fun. Although I swear I have seen outright murder glee in some cats' eyes, almost to the blazing meme degree.

Three different state universities. The top two in the state, with an intense rivalry, have, or had, the bright eyes. I am familiar with one- the bright but with a side of criminal- has been sued into SJW genuflecting, and now has diversity.

The other bright one, I've never been to. They collect world-changing people who accomplish great things, and now the white kids preferentially go there. It's the one where everyone is friendly, somehow, and you are either in or ill at the place. I've never been. There are people who visit and leave and never go back "Nice, but not for me" while graduates of the place arrange for their ashes to be spread on the campus ash field overlooking the football stadium.

The third is a second tier school that is clawing its way up to first tier, by recruiting specific scholars in specific areas, and picking up all the kids that don't want to deal with the diversity circus.

People have families with kids in all three schools, or cousins. The kids are all different, somehow, but related, and very different than kids from other states.

What's interesting is that the HBCUs kind of have the same breakdown. I wonder if the ones on the East Coast have similar characteristics.

You imply a good point. It's not good to read human emotions in animals.

I saw a vole out match my tuxedo cat (tuxedos are known for a high prey drive). It was kind of funny seeing this little rodent stand up straight and bite my cat. He killed tens of elevens of voles that year though.

I can easily spot what I call "empty eyes" on less intelligent people. People with "empty eyes" are just NPC's that have less development time devoted to their dialog trees.
